LOOM REED MOTION AND MECHANISM Filed Oct. 26, 1929 Patented June 30, 1931 UNITED STATES PATENT OFFICE HUBERT HAYWOOD, OF WIRKSWORTH, ENGLAND, ASSIGNOR T THE HAYWOOD NAB- ROW FABRIC LOOM COMPANY LIMITED, OF THE HAGUE, BROADBOTTOM, CHESTER ENGLAND LOOM REED MOTION AND MECHANISM Application filed October 26, 1929, Serial No. 402,764, and in Great Britain February 1G, 1929.

This invention relates to improvements in swinging arm to prevent vibration of the pin the reed motions of smallware looms of the type in which the reeds are carried by swinging arms having curved slots at the lower f5 ends and actuated by pins eccentrically mounted on a continuously rotating disc and working in the curved slots so that the motion of the reeds is retarded during the passage of the shuttles through the warps.

It is found that at high speeds there is a certain amount of vibration or chattering of the pin in the curved slot of the swinging arm particularly at the point where the action changes from acceleration to retardal tion and to overcome such vibration a slide is aHiXed on the pin of the same curvature as the slot so that it will slide therein.

The invention will be described with reference to the accompanying drawing which shows a side elevation the swinging arm carrying the reed.

As in the known form of reed motion to which this invention relates the swinging arm C carrying the reed F is actuated by a disc A continuously rotating in one direction and carrying an eccentrica-Hy mounted pin a which engages in a curved slot B at the lower end Cl of the arm C.

To prevent chattering or vibration at high speeds of the pin a in the slot B, a slide A1 is pivotally mounted on the pin a to `engage in the slot B, the slide being of the same curvature as the slot so that it will slide therein. The ends of the slot B are made suficiently long to accommodate the ends of the slide A1 when the pin a is at the top or bottom of its movement relative to the slot B so that the p-in will occupy the same position in the slot as when no slide is affixed thereon.

What I claim as my invention and desire to protect by Letters Patent is:

In a reed motion of the type referred to for smallware looms the combination with the slotted swinging arms, the continuously rotating discs and the pins working in the slots at the ends of the arms of a curved slide pivotally mounted in relation to the disc and carried on each pin, the curvature of the slide being the same as that of the slot in the therein.
